Isaev, AlekseiMikhailovich - (1908-1971) - Soviet designer, a specialist in the field of rocket engines, PhD (1959), Hero of Socialist Labor (1956) ... After graduating in 1932, the Moscow Mining Institute, worked on major new buildings and in the project ornanizatsiyah country. Since 1934, the aviation industry, working in CB VF. Bolkhovitinov, Isaev, together with birch designed and built a prototype rocket plane - fighter BI-1 (1942). In 1942 developed the rocket engines, since 1944 - Chief Designer KB. Isaev in 1946, first applied to the rocket engine, flat head with a checkerboard arrangement of one-component jets, which allowed to obtain a high completeness of the combustion. This head design has found wide application in the rocket engine technology.. In 1950-52 under the leadership Isaeva first in the USSR were established gasifiers (HS), who worked on the bipropellant with a large excess of fuel or oxidizer. HS of this type have found application in replace. fuel delivery systems (liquid-accumulator pressure) to drive the turbopump turbine and boost fuel tanks, as well as RD closed schemes proposed Isayev.

In 1950, at the head of the chamber rocket engine on the proposal Isaeva first began to use antipulsatsionnye walls, allowing in many cases, eliminate high-frequency oscillations of pressure in the chamber. In 1957, Isaev applied narezemnye (welded) connection units of the engine, completing the job of building the first all-welded LRE. Under the guidance of established Isayev rocket engine and control for missile and space technology, including the spacecraft Vostok, Voskhod and Soyuz spacecraft series "Moon, Mars, Venus," "Probe," "Lightning "" Flight "," Cosmos ", orbital stations Salyut and others. Lenin Prize (1958), USSR State Prize (1948, 1968). Awarded 4 orders of Lenin, Order of the October Revolution, and medals. Name Isaeva named a crater on the Moon.
